Merriwa River

Merriwa River, a perennial river of the Hunter River catchment, is located in the Upper Hunter region of New South Wales, Australia.

Course and features
Merriwa River rises on the southern slopes of the Great Dividing Range, below Oxleys Peak, north of Merriwa and flows generally south, joined by eight minor tributaries before reaching its confluence with the Goulburn River below Mount Kerrabee. The river descends 317 m over its 78 km course.

At the town of Merriwa, the Golden Highway crosses the Merriwa River.

Merriwa is thought to be derived from the Aboriginal word meaning "grass seeds."
